treeview: Order

Hi Codegurus,

I hope someone of you can help me.

I'm not so good in english, because I'm from germany, so excuse my bad english please.

I have a treeview with some nodes in it.
now I want to order it alphabetically, and use order=true on each node.
But now I want to restore the original order. by setting order=false nothing changes.
I would do it by own code, but I don't know how to move a node up or down in the treeview.
I'va tried to use the "next" or "previous" propertie, but they are read-only.
I cannot simply remove and then again add the nodes, because there are several subnodes.

if you can help me,
many thanks!

greetings,
Tom
